The word 'normal' is the main issue, I would argue. There's no normality in partaking or not for any of those things. Statistically likely, sure. But normal is nothing and the second you have 'normal' that starts making people 'not normal.'
I'm a bit hypersensitive to this sort of thing, as I've had actual friends treat me as abnormal for not wanting to drink. It was surprisingly difficult to convince them that I didn't need to drink and they should respect my choice without demanding a goddamn explanation.
(though I only had to threaten one of them)
You'd think it would be a simple principle. I don't question their choices when it comes to that sort of thing, they shouldn't question mine.
Oh I totally get that sensitivity. I'm teetotal now, after a time of drinking to various degrees. I got drunk once when I was 14 or so and hated it so stopped and people were just aghast. It eventually became about digging my heels in. 'HOW CAN YOU HAVE FUN IF YOU DON'T DRINK?'
The very next drink I took, some five years later, was at university, when somebody asked me if I would like a drink rather than saying I had to have one. Once I'd made it through one party sober without anyone being an asshole about it, I experimented a bit more and eventually became a pretty gold-standard drunk for eight years or so, with a couple of years of 'unfortunate cocaine habit' in there too.
Nowadays I'm teetotal again outside of maybe a double Scotch on a special occasion, and to this day I do still get shit about it.
TL;DR: I get completely where you were coming from. I was endeavouring to broaden the scope of what you were saying.
